    Abstract

    The applicability of pyrolysis—gas chromatography to isothermal solid state kinetic studies is discussed based on a model comprising primary formation of volatiles and a non-volatile fraction, the latter being converted into volatiles and an eventual non-pyrolyzable fraction in secondary reactions. The nth order kinetic approach to solid state reactions is illustrated by studies on the pyrolysis of coal. The significance of the obtained activation parameters, including the activation entropy, is discussed.
